Resurface, replaster and remodel are three jobs and three sets of searchers
The renovation half of your business contains more distinct search intent than the new build half, and most builder sites collapse all of it onto one page.
A homeowner in Richardson with a 1985 pool rarely searches for a pool builder. She searches for pool resurfacing cost, plaster flaking off, replacing pool tile, or whether her pool can get a spa added.
Give each of those its own page. Finish replacement, tile and coping, deck tear out and replacement, equipment upgrade, adding a spa or a tanning ledge, converting to saltwater, and a full remodel that changes shape or depth are separate decisions with separate budgets.
Write each page in the language of the job rather than the language of your estimating software. If your crew calls it a replaster and the homeowner calls it resurfacing, the page needs both words, used naturally.
Renovation pages also behave differently over time. New build interest concentrates in a season, while a failing heater or a cracked coping generates a search the week it happens. A site built only around new construction goes quiet for months at a time.
